Most smokers pick these because they are used with e-cigs that resemble a traditional cigarette. When you inhale through a device with an automatic battery, it detects this rush of air and turns the battery on. A manual battery has a button that you press to activate. If you like a device that stands out and fits your style, there are many more choices than the boring white or black batteries. They come in all sorts of colors and styles. You can easily find one that matches your vaping preference. Some vapers are confused by a batteries capacity and a batteries voltage. The capacity is measured in mAh.

Keep all of this in mind while you’re vaping with your new device.
